STEAM-CONDENSER.

Specification of Letters Patent.

Patented Apr. 2, 1912.

Application filed June 22, 1911. Serial No. 634,822.

To all whom it may concern:

Be it known that I, FREDERICK HAUs- WIRTH, citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful, Improvements in Steam-Condensers, of which the following is a full, clear, and exact descrip- -tion, reference being had to the accompanying drawings, forming a part hereof.

My lnvention has relation to lmprovements in steam condensers; and 1t consists in the novel details of construction more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a longitudi nal section (with parts in elevation) through the center of the condenser showing cooling coils and storage-tank attached thereto; Fig. 2 is an end elevation of the condenser; Fig. 3 is a vertical section on the line 3-8 of Fig. l; and Fig. 4 is a horizontal section on the line 4 t of Fig. 1, with bottom pan omitted.

The object of my invention is to provide a steam condenser that, in addition to condensing the steam, will perform the desirable functions of reboiling and skimming the condensed steam.

A further object is to provide a steam condenser that will not be burdened by numerous and complicated parts,.but, nevertheless, be capable of the utmost efliciency, and one possessing further and other advantages better apparent from a detailed description of the invention, which is as follows:

Referring to the drawings, 1 represents the steam pipe which conducts the steam from the exhaust of the engine (not shown) into the condensing chamber 2. Immediately upon entering the chamber 2, the steam, being free to expand, finds its way through the chamber as indicated by the arrows, as it is. deflected by the trough or gutter-shaped baffles 3. The notched trough T, being supplied by water from a pipe P, overflows onto the outside of the condensing chamber, thus keeping it covered with running water and causing the steam to condense on the inner walls of said chamber, the water of condensation draining onto the inclined walls of the baflies 3, and collecting over the center row of perforations 0 of said ba'lfles, through which it drips and finally collects in the main bottom compartment G of the condenser, the condensed water subsequently reboiling by contactwith the hot steam pipe 1 normally submerged therein, the level of the water being indicated by the dotted line m, Fig. 1.

Contiguous to the compartment C is the waste-compartment C, these compartments being separated by the partition wall 4. Any foreign matter that may find its way through the steam pipe 1, will drop into the compartment 0 as soon as it leaves the elbow 1. If however, a foreign substance (such as oil) is held in suspension by the steam until after passing above the compartment C, it will remain on the surface of the water accumulating in said compartment, and overflow into compartment C when the water in the compartment 0 reaches the level indicated by the dotted line in (Fig. 1). The waste products accumulating in compartment 0 are drained ofi' by means of the pipe 5. 1

Secured to the side walls to of the condensing chamber 2, and directly above the compartment C, are V-shaped troughs or gutters 6. These troughs are intended to intercept the condensed steam which may gather on the walls of the condenser above the waste compartment C, and guide it into the compartment O, thereby preventing a loss of this portion of the condensed. steam. The troughs 6 incline as shown,

toward the compartment G, and project beyond the wall I The condenser is supported by the standards S said standards resting in a large ,pan R which receives the cooling water after it is deflected from the condenser by means of the deflectors 7, placed on each side of the condenser. These deflectors are so placed as to prevent the water which runs over the condenser from adhering'to that portion of the sides which form part of the compartment 0. It is readily seen, therefore, that the compartment G is not. cooled, but remains filled with hot water, this water reboiling on account of the heat in the pipe 1. Tapping the bottom of the compartment 0 is a pipe 8 through which the hot water is fed to the cooler 9, then into the supplyv or storage tank 10. The float valve 11 controls the supply-tank feed so that a constant level is maintained therein, it being desirable not to waste the water after it has been cooled, any oversupply being allowed to pass away in the condensing chamber before the cooling takes place.

It may be stated in passing that the condenser here described is eminently adapted in connection with ice machines, the water of condensation from the exhausts of the engines operating the ammonia compressors being stored in the cooling tank 10. Once this water is cooled it should not be wasted, since it is the cool water from the tank 10 which is returned to the molds in which the water is frozen to make artificial ice. Should therefore, the feed into the tank 10 be too rapid, such feed is automatically cut off by the float-valve 11 (as well understood in the art), the excess being discharged as hot water from the overflow compartment C of the condenser 2. It may be further stated in passing that the object of boiling the water condensed in the vessel 2 and accumulating in the compartment C is to rid such water of all impurities, particularly lubricating oil from the machinery, the boiling bringing such oil (and other impurities) to the surface where it flows over the edge of the partition 4: (availed of to support the inner end of the pipe 1) into the overflow or waste compartment C, whence the oil and other impurities, mixed with water of condensation are conducted to the sewer or other place through the waste pipe 5. Since, therefore, it is desirable that the water in the compartment C be reboiled (after once condensed) for the purpose here indicated, it is obvious that we should maintain the walls of the compartment at as high a temperature as possible; and it is for this reason that the deflectors 7 are availed of, said deflectors preventing the cold water flowing from the trough T over the outer walls of the condenser, from contacting with the walls of the compartment C, the said water being deflected outwardly and directed into the pan R. The pipe 25 is a vent pipe for the chamber 2, allowing free communication between the outer at mosphere and the interior of the condenser.

Features shown but not referred to are well known in the art and require no de scription in the present connection.

The operation is clear from the description, but briefly stated, is as follows :The exhaust steam. from the compressor (or other) engine is conducted through the pipe 1 into the condenser 2 over which cold water is flowing from the trough T, the water being deflected by the plates 7 as described. As the steam within the chamber 2 condenses, it trickles down to and through the troughshaped deflectors or bafiies 3, and down over the troughs 6 into the compartment C, where the condensed water in due time reboils by contact with the hot walls of the pipe 1, any impurities such as oil flowingover the edge of the partition wall 4 into the waste compartment C, a portion of the impurities mechanically suspended in the steam discharging from the elbow 1 being precipitated directly from the elbow into the compartment C. There is thus an initial precipitation of a portion of the impurities before the latter are carried into the upper portions of the chamber 2 whence they are removed by the boiling process as already described. For it must be obvious that ice for domestic purposes should be made of as pure water as possible. The baflles 3 serve to distribute the steam over a large area so that condensation shall take place to best advantage and in a minimum amount of time.

Having described my invention, what I claim is 1. A steam condenser comprising a condensing chamber provided with a compartment for accumulating the pure product of condensation, a compartment for accumulating the waste product, means for preventing the pure product from entering the waste compartment, means within the first compartment for reboiling the liquid therein, said means entering the waste compartment through the means which prevent the pure condensation product from entering said waste compartment.

2. A steam condenser comprising a con densing chamber provided with a compartment for accumulating the pure water of condensation, a waste compartment, an overflow partition separating the compartments, and a steam pipe in the first compartment passing through the partition into the waste compartment.

3. In a steam-condenser, a condensing chamber, means for conducting steam thereinto, said chamber being provided with contiguous compartments, means for effecting a precipitation of a part of the mechanically suspended impurities into one of said compartments, means for collecting the waters of condensation of the main volume of steam in the other compartment, means within the last named compartment for reboiling the water and means for conducting the impurities of such reboiled waters into the first compartment.

4. A steam-condenser comprising an outwardly water-cooled condensing chamber provided with a main bottom compartment for the collection of the waters of condensation, and with a contiguous Waste compartment separated therefrom by a partition wall, said compartments being provided with discharge means, a steam pipe disposed along the bottom of the main compartment and discharging through the partition wall into the waste compartment, gutters disposed on the inner walls of the chamber on each side of the discharge from the steam pipeand draining the waters of condensation over the partition Wall into the main compartmenhthe partition wall between the compartments bein of a height to allow for submergence of t e steam pipe within the main compartment whereby reboiling of the water therein is made possible, deflecting plates on the outside of the condensing chamber positioned in a plane over the main collecting compartment to prevent contact of the cooling water with the outer walls of said compartment, and means-in the condensing chamber for distributing the Copies of this patent may be obtained for In testimony whereof I aflix my signature, 20
